Therefore, high ionization levels and high electron densities could generate\nhigh-charge energetic electron beams. Our experiment has verified that clusters\nin the gas jet influence the laser propagation and Wakefield evolution, producing\nstable laser guiding and good quality electron beams.\nConclusion: The results demonstrated that the laser-driven clustered gas target\nprovides a unique method for electron injection and has great potential in\ngenerating mono-energetic collimated electron beams with large beam charge.\nStable and reproducible mono-energetic electron beams with sufficient electron\nintensities are required in medical applications, e.g., radiotherapy. Many\nengineering issues remain to be solved before clinical application, but laseraccelerated\nelectron beams present a promising scheme for future radiation\ntherapy.", "subitem_description_type": "Abstract"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "metadata only access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_14cb"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tao, Mengze"}], "nameIdentifiers": [{"nameIdentifier": "488919", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ホァン, カイ"}], "nameIdentifiers": [{"nameIdentifier": "488920", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Li, Dazhang"}], "nameIdentifiers": [{"nameIdentifier": "488921", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Li, Yifei"}], "nameIdentifiers": [{"nameIdentifier": "488922", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Guo, Xin"}], "nameIdentifiers": [{"nameIdentifier": "488923", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ma, Yong"}], "nameIdentifiers": [{"nameIdentifier": "488924", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Zhao, Jiarui"}], "nameIdentifiers": [{"nameIdentifier": "488925", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Li, Minghua"}], "nameIdentifiers": [{"nameIdentifier": "488926", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Wang, Jinguang"}], "nameIdentifiers": [{"nameIdentifier": "488927", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hafz, Nasr"}], "nameIdentifiers": [{"nameIdentifier": "488928", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Zhang, Jie"}], "nameIdentifiers": [{"nameIdentifier": "488929", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Chen, Liming"}], "nameIdentifiers": [{"nameIdentifier": "488930", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "黄 開", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "488931", "nameIdentifierScheme": "WEKO"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Quasi-Mono-Energetic Electron Beams from a Laser–Driven Argon Clustered Gas Target for Radiation Medicine", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Quasi-Mono-Energetic Electron Beams from a Laser–Driven Argon Clustered Gas Target for Radiation Medicine"}]}, "item_type_id": "8", "owner": "1", "path": ["1"], "permalink_uri": "https://repo.qst.go.jp/records/48619", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-03-22"}, "publish_date": "2018-03-22", "publish_status": "0", "recid": "48619", "relation": {}, "relation_version_is_last": true, "title": ["Quasi-Mono-Energetic Electron Beams from a Laser–Driven Argon Clustered Gas Target for Radiation Medicine"], "weko_shared_id": -1}
